The Mercury 150XL is a robust four-stroke outboard motor designed for medium boats such as aluminum fishing boats, pontoons, inflatables, and cruisers up to 22-24 feet. Featuring a 25-inch extra-long shaft, it weighs 455 lbs, offering a balance of power and versatility in its 150 HP class. The 2500cc (152.6 cubic inch) inline four-cylinder engine with Electronic Fuel Injection (EFI) and 16-valve DOHC design delivers exceptional low-end torque for quick planing and a full throttle range of 5000-6000 RPM. Equipped with remote mechanical steering for precise control, electric start for effortless ignition, and power trim & tilt for easy adjustments. The motor features a 3.2-gallon external fuel tank, low-vibration mounts for smooth operation, and a 60-amp alternator to support electronics. Built for durability in freshwater and saltwater, it uses low-copper aluminum alloys, stainless steel components, and a multi-layered priming and painting process for superior corrosion resistance. With reliable starting, instant throttle response, and fuel efficiency, the 150XL is ideal for versatile, worry-free boating.

3 reviews for Mercury 150hp 25″ Shaft | 150XL
Rules coastal runs on my rig—the 150XL’s EFI for instant torque, under 6 gph cruise extends range, hits 40 mph with gear. Ultra-quiet with zero vibes for all-day comfort. 80 hours in salt, black finish holds up—lightest, most maintainable 150hp out there!
Trailering this 465-lb powerhouse is simple, and on the water, the 150XL dominates. Battery-free starts, low-RPM thrust for hefty hulls, EFI smarts for efficiency. Tops 38 mph loaded, silent inline-4 for serene vibes. Durable finish for tough conditions—Mercury’s 150hp redefines power-to-weight!
The 150XL is a beast on my 21-foot bass boat—465 lbs feels light for the power, and the 25″ shaft with power trim handles deep water like a pro. EFI starts instantly, no battery needed, even in early morning chill. Trolled for stripers all day on under 7 gallons, hitting 41 mph at 5800 rpm solo. Quiet inline-4 with rugged finish—Mercury’s 3.0L torque blows past my old 150!
